Interstitial fallopian tube obstruction (IFTO) occurs in 15% of hysterosalpingograms (HSG) performed for infertility. Conventional HSG or laparoscopy may not differentiate cornual spasm or other temporary cause from true obstruction. We used transcervical cannulation of the proximal oviduct with a 3-F Teflon catheter and flexible guidewire 0.018 inch (0.043 cm) in diameter under hysteroscopic or fluoroscopic guidance to evaluate IFTO in 28 patients. Fluoroscopic catheterization techniques with selective salpingography demonstrated patency in 84% of obstructed tubes. Hysteroscopic cannulation with direct visualization by laparoscopy or laparotomy was successful in 92%. In one patient, perforation of the isthmus occurred without sequelae. Transcervical coaxial cannulation of the proximal oviduct is an effective method for evaluating cornual obstruction.
间质部输卵管阻塞（IFTO）在因不孕症而行子宫输卵管造影（HSG）的患者中发生率为15%。传统的HSG或腹腔镜检查可能无法区分子宫角痉挛或其他暂时性原因与真正的阻塞。我们在宫腔镜或荧光镜引导下，使用直径为0.018英寸（0.043厘米）的3-F聚四氟乙烯导管和柔性导丝对近端输卵管进行经宫颈插管，以评估28例患者的IFTO。采用选择性输卵管造影的荧光镜插管技术显示，84%的阻塞输卵管通畅。通过腹腔镜或剖腹手术直接观察的宫腔镜插管成功率为92%。1例患者发生峡部穿孔，但无后遗症。近端输卵管经宫颈同轴插管是评估子宫角阻塞的有效方法。
